I have a 10x10 chain link dog pen that I'd like to use for bob whites. Will the whole thing need hardware cloth to keep them in it or will something smaller (and cheaper) work? What should I use for the top? I know I'll need to bury wire fencing also to keep out digging predators. I have a wood house (predator proof) for them to go into also that is about 2 feet wide, 4 week long, and 2.5 feet high. Will they go in it to roost at night? How do they generally sleep? Indoors like the chickens do, or will they be roosting outdoors in the fight pen?
